Description

Technical Field

[0001] The utility model relates to the field of lens coating machines, in particular to an optical glass lens coating device. Background Art

[0002] During the lens production process, a layer of film is applied to the lens through a vacuum coating machine in order to increase light transmittance and reduce reflection, protect against ultraviolet radiation and blue light, improve hardness and wear resistance, and increase aesthetics and comfort. A vacuum coating machine is a commonly used device for lens coating. It can evaporate or sputter metal or non-metal materials onto the surface of the optical element to be coated in a vacuum environment by using methods such as electron beam evaporation or magnetron sputtering.

[0003] At present, the vacuum coating machine mainly includes a vacuum chamber, a vacuum system (including vacuum pumps, valves, pipelines, etc.), a coating source, a substrate rack, an electronic control system, a monitoring instrument, etc. The lens and other materials to be coated are supported by the substrate rack and placed in a vacuum chamber. The gas in the vacuum chamber is discharged by the vacuum system to create a vacuum environment. Under the action of the coating source (such as an electronic evaporator), the metal or non-metallic material is evaporated and deposited on the object to be coated. The key parameters of the coating are monitored in real time by the monitoring instrument, and the electronic control system controls the operation of the coating machine. The specific structure of the vacuum coating machine can refer to a vacuum evaporation machine disclosed in a Chinese patent with publication number CN112626486B, which includes: an evaporation machine body, a heating lamp structure, a plating pot structure, a water-cooled insulation mechanism, a crucible, an ion source, a control mechanism, and a driving mechanism. The interior of the evaporation machine body is divided into an evaporation cavity and a control component cavity. The heating lamp structure, the plating pot structure, the water-cooled insulation mechanism, the crucible, the ion source and the driving mechanism are all arranged in the evaporation cavity, and the control mechanism is arranged in the control component cavity. The driving mechanism includes a motor and a vacuum pump group. A main valve cavity is provided on one side of the evaporation cavity. A vacuum pump group connected to the main valve cavity through a vacuum tube is provided at the lower part of the main valve cavity. The vacuum pump group is located on a bracket outside the evaporation machine body. The evaporation cavity is a hollow cylinder or a hollow elliptical cylinder.

[0004] When the above-mentioned vacuum coating machine is used to coat the lens, the lens needs to be supported on a substrate rack, and the lens is stably placed in the vacuum chamber under the support of the substrate rack. However, it is known from actual processing that the space of the vacuum chamber is relatively large, and the substrate rack is generally arranged at the top of the vacuum chamber, while the coating source is arranged at the bottom of the vacuum coating machine. Then, after the substrate rack is installed in the vacuum chamber, a large gap is left between the substrate rack and the bottom of the vacuum chamber, resulting in a waste of space, which is not conducive to the coating treatment of batch lenses, that is, the efficiency of the coating treatment is low. If the number of substrate racks can be increased or decreased according to actual needs, the space of the vacuum chamber can be fully utilized, which can provide support for the coating treatment of batch lenses.

[0026] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0027] Example 1

[0028] As described in the background technology, after a substrate rack is placed in the vacuum chamber of an existing vacuum coating machine, a large gap is left between the substrate rack and the vacuum chamber. If the gap can be fully utilized and the number of substrate racks can be increased or decreased according to demand, it will provide convenience for improving the coating process of batch lenses. In order to achieve this purpose, this embodiment improves the substrate rack on the basis of the existing vacuum coating machine to obtain this technical solution.

[0029] like Figure 1 As shown in the figure, since the vacuum coating machine has been made public, a brief introduction to the vacuum coating machine is given here. The vacuum coating machine includes a vacuum chamber, a vacuum system, a coating source, a substrate rack, an electronic control system, a monitoring instrument, etc. The vacuum chamber is the main part of the coating machine, which is used to accommodate the objects to be coated and the coating process. The vacuum chamber is usually made of stainless steel or aluminum alloy to ensure that it is rust-free and solid. According to the different requirements of the processed products, the size of the vacuum chamber is also different. The diameters of 1.3M, 0.9M, 1.5M, 1.8M, etc. are currently more commonly used. There are connecting valves in each part of the vacuum chamber for connecting each exhaust pump. The vacuum system includes vacuum pumps, valves, pipelines and other equipment. Among them, the vacuum pump can be selected according to specific needs, such as centrifugal pumps, molecular pumps, etc. In addition, the exhaust system is an important part of the vacuum system of the coating machine, which is mainly composed of mechanical pumps, booster pumps (such as Roots pumps), oil diffusion pumps, etc. This system adopts a combination of "diffusion pumps + mechanical pumps + Roots pumps + cryogenic cold traps + polycold". The mechanical pump first evacuates the vacuum chamber to a low vacuum state, providing a prerequisite for the subsequent vacuum pumping by the diffusion pump. Afterwards, when the diffusion pump evacuates the vacuum chamber, the mechanical pump cooperates with the oil diffusion pump in series to complete the pumping action. The coating source is used to generate coating material vapor or ion beam so that it can be deposited on the surface of the object. Common coating sources include electron beam evaporators, etc. The electronic control system is used to control the working process of the coating machine, including controlling the switch and operating status of the vacuum system, coating source and other equipment, to achieve automatic control of the coating process. The substrate rack is used to support the object to be coated. In the following, the vacuum coating machine is collectively referred to as the vacuum coating machine body 1, and the vacuum coating machine body 1 does not include a substrate rack.

The supporting plate 6 is also configured as a curved surface structure, and is placed in the mounting hole 41, and the curved surface is located on the same curved surface as the curved surface of the bracket 4. The supporting plate 6 and the bracket 4 are detachably arranged, so that the supporting plate 6 can be replaced according to needs, so as to adapt to lenses of different sizes, and provide convenience for expanding the practicality of the supporting assembly 2.

An annular plate 63 is provided in each placement hole 62, and the annular plate 63 is provided at the bottom of the placement hole 62. When placing the lens on the supporting plate 6, the lens is placed in the placement hole 62, and the lens is supported on the annular plate 63, so that the lens is stably placed relative to the supporting plate 6.

[0032] like Figure 2 , Figure 8 As shown, in order to stably install the supporting assembly 2 in the vacuum chamber, a top column 3 is arranged above the supporting assembly 2, the top of the top column 3 is connected to the top of the vacuum chamber, and the bottom surface of the top column 3 is provided with a first thread groove 31, and the top thread of the screw 51 is inserted into the first thread groove 31.

Under the action of the connecting mechanism 5, other supporting assemblies 2 can be detachably arranged below the uppermost supporting assembly 2, which provides convenience for adjusting the number of supporting assemblies 2 according to needs and provides support for improving the coating efficiency of the lens.
